Index function not working during matching

Sauda — Thu, 16 Nov 2017 18:58:07 GMT

Hi Expert,

I asked this question yesterday and got the result.

I manipulated few data today but the output is not working correctly.

My criteria is to retrieve records from child table when country, product (using like operator logic) and dosage matches with same variable in table parent.

For combination of product, I don't want those records like 105

e.g. product mention in child table for record 105 is Gelusil where as the same product is available in parent table as in combination (Gelusil+Amlopidine).

How to ignore this type of records for this column or any alternative

data Child;
input pid country $ product & $25. dosage $;
cards;
101 France Atorvastatin          Oral
102 France PaRacetamol            .
103 Russia Nimusulide injection  sc
104 China DIovan                 Tablet
105 Japan Gelusil                Tablet
106 India Codeine+phosphate      Tablet 
;
run;

data Parent;
input country $ product & $25. dosage $;
cards;
JapaN Atorvastatin calcium 		Oral
China Atorvastatin 				Oral   
France Atorvastatin calcium 	Oral   
Russia Paracetamol 				Oral   
India Paracetamol 				Oral   
France Paracetamol 				Oral   
RusSia Nimusulide 				sc   
China diovan Syrup   			.
China diovan 					.
Japan Gelusil+Amlopidine     	Tablet
india Codeine+phosphate+salt    Tablet
Japan Gelusil Tablet			.
;
run;

proc sql;
  create table match_country_prod_dos as
  select A.*
  from   CHILD A
  where  exists(select distinct B.COUNTRY from PARENT B where (upcase(strip(B.COUNTRY))=upcase(strip(A.COUNTRY)) 
                  and index(upcase(strip(B.DOSAGE)), upcase(strip(A.DOSAGE))) >0 and index(upcase(strip(B.PRODUCT)),upcase(strip(A.PRODUCT)))>0));
quit;

Your program does not output line 105.

So confusing....

You state that you want to exclude 105, but you already are excluding it.

What do you want?

Please post the desired output.

If you run the complete program, I am getting three records like below.

How can I skip record number 105 as the child table contain product name as Gelusil where as parent contain combined product i.e. Gelusil+Amlopidine.

I want only output for record number 101 and 106 which is matching with parent table.
